On my H18mag I had "footstraps sewn onto the wing covers. My friend used the "screwed on" type using SS #10 screws, they can be pulled off as the screws pass through the holes in the straps. Sewing them on using 2"-3"wide nylon webbing, double layerd w/ some rope or plastic in the middle to add "stiffness" works well except you have to be careful keeping the footstraps properly in-place when lacing the wings. This can take a little effort to get correct.

How are you making out w/ "hooking" that Mainsail ... OMmmmm ... OMmmmm
